Fortran
I write numerical codes for my research in Fortran.
This may mean that I qualify as a
real programmer. If you are having
problems with Fortran, drop into my office (W2.38c) and
I’ll make them worse. I can make even the dustiest old
code acceptable to modern compilers.
Personally, I recommend the NAG Fortran compiler,
which I help to test and debug. You might prefer the Gnu compiler
which is free (but tends to lag behind NAG in development).
Some interesting code that might be useful:
-
Click here for
details of polygone, a program which can
drastically reduce the size of certain postscript
graphics files, such as those produced by the
ContourPlot and ListContourPlot commands in Mathematica
6 and later.
-
Click here to download
exp_integral_standalone.f90, which computes exponential integrals of complex arguments using
the algorithm developed by D. E. Amos (see papers
here and
here).
Essentially it's a Fortran 2003 version of
ACM Transactions on Mathematical Software algorithm 683, the original
(FORTRAN 77) code for which is available
here.
-
Click here to download filon_quadrature.f90, which computes certain oscillatory
integrals using an adaptive scheme.
It accompanies the article
‘From Simpson to Kronrod — an elementary approach to quadrature formulae’,
which appeared in volume 46(6) of Mathematics Today
magazine.
Miscellaneous
-
I can usually sort out problems with gnuplot and
LaTeX (including some postscript and pdf problems) as well.
If your problem relates to figure/table placement in LaTeX, please read
this
before paying me a visit.
-
I learned HTML by right-clicking on other people’s web sites and
selecting ‘view [page] source’.
It's becoming increasingly difficult to do this because you don’t
always get all of the files on which a page depends when you save it.
All files on which this page depends are located in the following directories:
